Application mapping of disseminated intellectual property into Network on Chip (NoC) is a well-defined NP-Hard problem. Improvement of network performance in NoC is purely based on an effective mapping approach with cost and performance metrics optimization which includes area, power, delay, reliability, and thermal distribution. A self-adaptive mapping approach for NoC is proposed in this paper. In this method, the self-adaptive chicken swarm optimization algorithm (SCSO) is used for an effective mapping, which has never been applied with NoC. The proposed method reduces the power consumption of NoC through a cognitive base using shared K-nearest neighbor clustering method and it offers faster mapping over standard and randomly generated benchmarks. The experimental results indicate that the proposed method outperforms existing bio-inspired metaheuristic algorithms, especially for large application graph.

Due to increased demands for communication at low power, an efficient application mapping has become vital in the area of network on chip (NoC). Optimisation of architectural structure in on-chip design is essential to maximise the performance of the network and minimise the cost functions. To address this issue, a knowledge-based memetic algorithm (KBMA) is proposed for 3D NoC for successful mapping with standard network topologies. The proposed KBMA adopts power, area and delay as a cost function for an effective mapping. The competence of the proposed method is verified through comparison with other natural inspired algorithms like particle swarm optimisation and genetic algorithm. The presented work is validated through four case studies which include real application benchmarks of NoC and random generated benchmarks using test graph for free.
